An organosilicon compound having a structure represented by following general formula:R1: methyl group or ethyl group, R2: a branched or linear, saturated or unsaturated aliphatic hydrocarbon group having 3 to 8 carbon atoms, n: 0. The machine includes an edger device for forming a bevel in a peripheral edge of the lens blank, a central processing unit operably associated with the edger device for controlling operation thereof, and a computer program stored on a medium in communication with the central processing unit. The deburring material has a durometer hardness and consequently a coefficient of friction whereby frictional engagement of a burr with the deburring material is stronger than the attachment of the burr to the workpiece and therefore the burr is removed as the deburring material is actuated and brought into contact with the burr. The method further includes configuring the cuff to tighten around the urethra when pulling on the first end of the non-porous sheet, and configuring the cuff to be loosely positioned around the urethra when pulling on the extending member. The buffer cell cluster has two distal ends.
